If considering the free expansion of an ideal gas adibatically such that the final volume is double of the initial volume.
Since dU=0 for free expansion ,which implies Ti=Tf for ideal gas...(1)
From adiabatic relation ,
TiViγ-1=TfVfγ-1, to satisfy (1) ,γ-1=0
and for ideal gas Cp-Cv=nR
or, γ-1=nR/Cv
And hence nR/Cv→0,
Or ,Cv→∞,?
